INCANDESCENT GAS-BURNER.

SPECIFICATION formingpart of Letters Patent No. 738,512, dated September 8, 1903.

Application filed December 27,1902. Serial No. 186,824. (No model.)

To (0Z6 whom it may concern:

Beit known that I, .ADOLF BAOHNER, a subject of the Emperor of Russia, and a resident of Frankfort-on-the-Main, in the Empire of Germany, have invented certain new and useful Improvements in Incandescent Gas-Burners, of which the following is a specification.

Many attempts have been made heretofore to construct incandescent gas-burners which have the appearance of burning downward and which are generally known as the inverted type. They have, however, met with comparatively little success, because the downward stream of mixed gas and air has hitherto been unable to entirely envelop the mantle, and thereby render the whole of it incandescent when the gas was ignited.

This invention relates to a lamp for incandescent gas-lighting, and has for its object to provide a lamp which presents the appearance of burning downward and which resembles an electric lamp and to provide means whereby the mixture of gas'and air is directed against the sides of the incandescent mantle, so as to completely envelop the same; and for this purpose the invention consists of an incandescentgas-burner comprisingasupplytube, a gas and air mixing chamber, a tubular support at oneend of the mixing-chamber for supporting the incandescent mantle, and a baffle-plate supported at the lower end of the mantle for deflecting the mixture of gas and air against the sides of the mantle, as will be more fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central section of an incandescent gas-lamp embodying my improvement. Fig. 2 is a section on line A Hot Fig. 1. Fig. 3

Referring to the drawings, a represents the supply-tube through which gas enters to the nozzle 1), from which it passes into the mixing chamber 0, while the air required for insuring a good mixture entersthrough the orifices (Z.

The mixing-chamber terminates in a tube f, to the lower end of which a tubular support 9 is attached by means of a bayonet-joint, so as to permit it to be easily removed and be replaced by a new support. This inter changeability renders the support independent of the lamp, which offers certain advantages, as the support may be easily removed for repairing. From the tubular support g depend supporting-rods h, which carry a cap-- shades 0 may be employed to increase the similarity to electric lamps. The regulation of the gas-supply entering themixing-chamher is effected by means of valves, regulating-cocks, screws, and the like in the usual manner.

In the modification shown in Fig. 3 the supply-valve is operated by a rod 19, which terminates in a milled head (1 for conveniently .turning the same.

The action of the device is as follows: The current of mixed gas and air emerges from the tube fand flows against the baffle-plate Z, by which it is deflected and caused to'flow radially toward the circumference of the baflie-plate and against the mantle which overhangs it, whereby the same is uniformly enveloped from all sides by the mixture.

The capsule i and the baffle-plate Z are preferably made of transparent material, shuc as glass, mica,and the like, for avoiding as much as possible the formation of shadows underneath the lamp.

Should it be desired to protect the lamp in a more thorough manner against external influences, in particular against drafts, the downwardly-flowing gas is so guided that instead of at once issuing into the opening at the lower part of the tube f, as shown in Fig. 1, it passes down an extension-tube .e and is guided thereby to the baflie-plate Z, as shown in Fig. 4.

Which in turn is connected with the gas-sup- IO ply tube. For the purpose of easily adj usting the mantle the tube .2 is screw-threaded, While the tubular support t, which is provided with books 3, is also screw-threaded, and so adapted to be moved up and, down.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent'- 1. An incandescent gas-burner of the inverted type, comprising a supply-tube, a gas and air mixing chamber, an incandescent mantle, a tubular support at one end of the mixing-chamber for supporting the incandes cent mantle, and a baffle-plate supported at the lower end of the mantle for deflecting the mixture of gas and air against the sides of the incandescent mantle, substantially 'as set forth.

2. An incandescent gas-burner of the inverted type, comprising a supply-tube, agas and air mixing chamber, a tube at one end of the mixing-chamber,an incandescent mantle, a tubular support removably connected with said tube, hooks on said tubular support for supporting the incandescent mantle, and a baffle-plate supported at the lower end of the mantle for deflecting the mixture of gas and air against the sides of the incandescent man tle, substantially as set forth.

3. An incandescent gas-burner of the inverted type, comprising a supply-tube, a gas and air mixing chamber, an incandescent mantle, a tubular support at one end of the mixing-chamber for supporting the incandescent mantle, a baflie-plate supported at the lower end of the incandescent mantle for deflecting the mixture of gas and air against the sides of the mantle, and means for raising or lowering the tubular support, substantially as setforth.

4. An incandescent gas-burner of the inverted type, comprising a supply-tube, a gas and air mixing chamber, an incandescent mantle, a tubular support at one end of the mixing chamber provided with means for supporting an incandescent mantle, a transparent capsule supported at the lower end of the mantle, and a baffle-plate in said capsule, substantially as set forth.

5. An incandescent gas-burner of the inverted type, comprising a supply-tube, a gas and air mixing chamber, an incandescent mantle, a tubular support at one end of the mixing-chamber for supporting an incandescent mantle, an extension-tube on said tubular support, and a baffle-plate at the lower end of the extension-tube, substantially as set forth. f

In testimony that I claim the foregoing as my invention Ihave signed my name in presence of three subscribing witnesses.

ADOLF BAOHNER.
